To all whom it may concern Be -1t known that I, JOHANNES IoNAz FRIEDRICH, a suh]ect of. the German Emperor. and resident of 145 Kurfiirstenstrasse,

-The present invention relates to a. ma-' chine for milkilfg the udder.

This machine operates essentially in such a manner that the milk is first moved from the'two udder-s being repeatedly stroked 1n aidowmrnrgl d irection under pressure by" the milkingeppztrntus after the udderhas been previnrsly .-sti mi.1 .ated" w by. kneiidings whereu p'onthe discharging of. the-tee ts" and 'cisterns'and the milking of. the .u 'd(.ler.- is effected by :rrepeated-compression and ex- 5 V pression of the udder increasing with the progressing discharge and a. downward stroking alongthe" udder hythe milkingappnra'tus simultaneous with a rocking and kneading'of the udders being pjroducedgand made to slightly squeeze down and out the tents, in order to completelydischarge the.

letter and remove'any drops ofmilk which may still adhere to the mouth'oftheteats. In the accompanying dnhv'ing the said. milking machineis exemplified in a conv is: disposed. 'lhe armfll is made. at'yit's end;

To a frame shaped main plate I, which; is rigidly secured by means of distancing bolts 1 to a. bottom plate 1", are pivoted in the shnneol' a: plate-22,

two levers 5 rocking on pins 6=in'the"plane of the plate, and drawn townrdezich other by a spring-Z fittedbetween-them.- To the ends of these levers 5 .are fitted pressing plates 8 betweenw'hich an'air-cushi0n9 is- Y both ebove and below on-pi ns2 sund y-the rocking plates 3 and 4; respectively.

To thegrocking' plate A are further pivoted twddoiuble-nrme dlevers 1O rocking in .a plane'parallel-tothe plateon 13. which are drawn by. springs '14 tow ardthe-rocking plate 4- is drawn. by a spring 16 secured to the said rocking plate Land the main plate, 1. i

'Ifh e arm 19 is curved-at-its end and provided .with v pins 3- :L plate 26. The pins "23 of the .pressfire plntes @tincrease in length with-each of th superimposed plates, and also the-strength ofthe springs may inereasein the same manner. Between the arms 20 and 321 are disposed inflatable air-cushions 27, against which press arms 21 by means of springs 28 which are secured to a pin on an arm 21 and to arm 19 respectively. The rocking plate 3, furthermore, has on its outer end a setscrew 29, which bears against the main plate 1, and between the two plates an inflatable air-cushion 30 is placed.

All air-cushions communicate by means of flexible tubes 31 with the cases 39. of piston-slides 33 which are reciprocated bv means of eccentrics 34 fitted to a shaft 37. The cases 32 communicate with a compressed air vessel 35, which is supplied with compressed air from an air-compressor 36. The four air-cushions 27 communicate with the same case 32, while the other three air-cushions 9, 13, 3O communicate each with a separate case 32. By means of the piston slides 33 the compressed air passing to the air-cushions is controlled in such a manner. that it will enter .in any desired manner and to any desired extent into the said aircushions or may be let off from the same respectively. a

In commencing the milking operation air is supplied and let off from the air-cushions 9 and 15 whereby'the udder milking apparatus 8 and 12. respectively, which grip the udder halves from inside and outside, the plates 8 passing up between the udder and moving apart, are pressed several times against the halves of the udder and moved up and down bv the rocking of plate 4. Then the teat milking apparatus 24, 26 are, by inflating of cushions 27 pressed repeatedly against the teats 40 between them. and likewise moved up and down by inflating and deflating the cushion 30. As, during this operation, the upper plates 24 are more forcibly pressed against the teats than the lower plates. the milk will be forced downward out of the teats. Then follows the clearing or after-milking by the plates 8 and 12 being repeatedly pressed in a more forcible man ner against the udder halves and therewith moved up and down. Lastly the milk, which might still be contained in the teats is drawn off by means of the lower milking apparatus in the hereinbefore described manner, so that the teats are completely discharged and any drops of milk adhering to the mouth of the teats are removed.

The teatand udder-milking apparatus are made of a light material and are so strapped by webbing passing over the back of the cow that they fit under the udder, while the other parts of the machine may be disposed in any suitable place. It is obvious that various changes may be made with respect to the construction of the above described machine without departing from the spiritof my invention.

I claim:

1. Machine for milking udders consisting of means movable in a horizontal and a vi": tical direction for operating on.. the teats and of means movable in a. horizoni ll. and a vertical direction for operating on the halves of the udder, which are gripped by the said means, means for operating said operating means.
